We used a Gentle Nodal Suspension (GeNS) system [1]} to measure coating mechanical loss, Young modulus and Poisson ratio via the direct measurement of the disk dilution factor [2]}. As a matter of fact, the dilution factor \(D\)  in Eq. (REF ) can be written as a function of the resonator mode frequency (\(f_0\) , \(f\) ) and mass (\(m_0\) , \(m\) ) before and after coating deposition, respectively [3]}:
\(D = 1 - \left( \frac{f_0}{f} \right)^2 \ \frac{m_0}{m} \ .\)
